Myinvention relates. to tie plates and more particularlyto tie .plates' of theoso called compression type, or, that is, of the i type such as illustrated Q and described in United States Letters Patent No. 1,219,224

-issued to Edwin H. Bellon- March 13, 192'? and No. 1,497,667 issued to William S. Boyceon June 17, 1924. p v

Tie plates of the compression, typehere: tofore have been characterized by having the median cessedand t en having arrangedin this-rethat the walls thereof forni'a pluralltyof tie enga ing "ribs extending Ilongitudinally,

. of the p ate. 'Whenj such it plate is putin use these longitudinally extending ribs initially enter between the fibi'esg of the tie f and as the lower surface of the-plate be-- comes embedded in thetie the} ribs com-- press thefibres into the compression grooves.-

Usually, the end-portions of such a plate were also recessed thereby creating a tie plate having two features of structure-which were sometimes objectionable because, name- 1y, first the end portions of the plate were weakenedand, second, the end portions of the plate could not contact? with the tie until the longitudinally extending formed by the walls of the compression grooves had been embedded in the tie by i the weight of passing trains and, therefore,

all of the weight of the rails and loads passing thereover was carried by the median portion of the plate until thelongitudinally extending ribs had been completely em- The objects of this inventionare to remove thes deficiencies of structure by providing a tie plate of the compression type of strong and rugged construction and in the use of .which the load carried by the plate" will be evenly distributed from end to end; r y A With these and other objectsin mind one embodiment ofmy invention is fullyshown in the accompanying drawings whereinsunf ilar characters are used to designate slmihar parts, Fig. 1 shows the bottom of thetie plate of this embodiment of my invention portion underneath thehrail re versely extending spaced apart members 3 arranged to initially seat on the tie. Each 'of the members 3 has a short rib 4 do ending therefrom, and arranged to be orced into the 'tie sufficiently to hold the late in position-while the rail .isbeing lai and spiked to the. tie. The bottom of the tie plate has a medlan recessed portion between the transversely extending members 3, and

plate beyond said members 3, all as shown 1n the ,figures In the recessed portions .5 and 6 areformed a plurality of compression grooves 7, preferably arcuate in cross section as shown, and the grooves 7 are arranged so, that'the walls thereof, meet, as shown in the figures, or are otherwise arranged to form a'plurality of longitudinallyextending tie engaging ribs 8. Preferably,- the lower edges of the tie engaging ribs 8 are m a plane coincident with the tie hearing surface of the transversel extendin members 3. The plate may provide with the usual spike holes 9.

The use and action of the tie plate shown and described is as follows: When the track is being laid the. tie plate is positioned on the tie and the short transverse ribs 4 are forced into the tiesufliciently to hold the plate in position while the rail is being laid and the spikes are being driven. The lower {surface of the transversely extending members 3 initially seat .on the tie, but as trains pass over the 'rail seated on the tie plate these initial bearing surfaces are forced into the tie and the longitudinally extending ribs .endreces sed. portions at each end of the r 8 enter between the fibres of the tie, as described-above, and as the members 3 become more firmly embedded in. the tie the fibres of the tie are compressed in the grooves 7.

It'will be noted that if the tie plate is formed as shown in the drawings the 1ongi- 1 tudinally extending ribs 8 inthe end recessed portions of the tie late engage the tie at the same time as tl fe ribs 8 1n the median" recessedfportion 5 and, therefore,

during the {time that the tie plate is becoming embedded in the tie the load is evena, ly distributed thoughout' the length -of the plate; H l
